Engine Performance problem
1996 Ford Ranger 4 cyl Two Wheel Drive Manual 160000 miles

I have a 1996 ford ranger. For 3 years in a row now I have had to replace the fuel pump. I get almost 1 year out of them and I have replaced it again. I drive down the road and it just quits. Sometimes it starts right back up and other times I have to wait an hour or so. I have replaced the relay, fuel pump, fuel filter, fuel presssure regular and even checked the shut off on the passenger side floorboard. It will not start. There is no fuel in the fuel rail. Any suggestions? I am so frustrated.
